SNOW-GUARD.-

SPECIFIOATION forming part of LettersPatent No. 529,774, dated November2'7, 1894.

Application filed August 24, 1894:-

To all whom it may concern:

Be it known that I, JOHN BAIRD, of the city of Paterson, in the countyof Passaic and State of New Jersey, have invented certain, new anduseful Improvements in Snow- Guards, of which the following is a full,clear, and exact description, such as will enable others skilledin theart to which it appertains to make and usethe same.

The invention relates to improvements in that class of snow guards inwhich rods or pipes are employed which rods and pipes are supported bystandards.

The object of my invention is to provide a snow guard which maybeadjusted or made to suit the pitch of any roof, and which from itssimplicity of construction, strength and the ease with which it ischanged to suit any pitch will obviate the necessity of having snowguards made especially for roofs of different pitches.

.The invention consists in the peculiar construction and combination ofparts shown in the accompanying drawings which form a part of thisspecification and set forth in the claims.

In my improved snow guard I employ an' adjustable standard which ispivotally secured at its base and an adjustable pivotally secured braceprovided with loops to admit bolts which pass through the sides of thestandards and through any of said loops in order to secure said brace tosaid standard.

I employ an ordinary metal plate which takes the place of a slate orshingle, and which is secured by nails or screws or other suitable meansat its upper end to the roof. At the bottom of said plate and to it Isecure two angle iron sides. The standard, which is the I shape of aninverted U is provided with holes in its sides to receive the guard rodsor pipes, and its ends are secured between said angle plates by means ofa bolt passing through said angle plates and ends. The ends of saidstandard are kept apart by means of a quill or thimble which is placedbetween them and through which the securing bolt also passes. As many ofthese bolts and thimbles may be passed through the sides of the standardas may be desired for the purpose of strengthening the standard. Theadjusting brace or bracket is formed by bending a piece of metal SerialNo. 521,202- (No model.)

on itself in order to form the loops for the adjusting bolt and an eyefor the swinging end of the adj usting brace is formed by the bending ofthe two ends of the, bracket metal. The swinging end of the adjustingbracket fits snuglybetween the said angle plates and is securedpivotally to them by means of a bolt which passes through the verticalsides of the angle plate and through said eye as shown in the drawings.

For the purpose of forming a strong guard for snow on pitched roots thestandards through which the pipes or bars pass are main tained in aperpendicular position by passing a bolt through the standards andthrough the particular loop of the adjusting bracket, which will attainthe object. It is thus obvious that my snow guard may be adjusted tovarious degrees of pitch which advantage has not to my knowledge beenhitherto attained. It is also obvious that by the peculiar constructionof my standard and extension brace or bracket great strength isobtained.

In the drawings Figure l is a perspective view of my snow guard. Fig. 2is afront elevation showing guide pipes or bars passing through thestandard.

A is the base plate; B-,the angle iron sides which are secured to thebase plate by bolts or rivets -B.

-O- is the inverted U shaped standard.

-G'- are the holes in the same for the guard tubes and O are the holesin the same for the adjusting bolts.

-D- is the adjusting bracket.

D are the loops formed to receive the adjusting bolt.

'-D is the adjusting bolt; D the nut securing the adjusting bolt and Dare rivets securing the loops.

-E is the eye formed by the two thicknesses of the bracket plate. E isthe securing nut of bolt passing through said eye and angle plates.

--F- is a quill or thimble of bolt -F -'-Fare nuts of the bolt F and -Fis the pivot bolt of standard and H- are the guard rods or pipes.

The standards and pipes are made of wrought iron and are calculated tohold back a pressure of at least six tons to each stand ard when placedfive feet apart and securely fastened to the roof. The standards may bepainted black or galvanized according to taste. The construction of thestandard C- secures great strength and at the same time allows snow topass through in melting.

My snow guard is thus cheap, simple and durable and calculated toaccomplish the object for which it is designed.

Having thus fully described the nature, construction, and operation ofmy invention, what I claim, and desire to secure by Letters Patent, is-

l. Asnow guard consisting of a metal base plate, angle iron side platessecured to said base plate, an adjustable brace or bracket pivotallysecured to said angle iron plates an inverted metal U shaped standardpivotally secured to the other ends of said angle iron side plates, thesaid adjustable brace having loops and the free end of said adjustablebrace passing through said standard, said standard being provided withopenings for an adjusting bolt and an adjusting bolt adapted to passthrough openings in standard and loop in ad- 3' Listing bracket, allconstructed substantially as shown and described and for the purposespecified.

2. In a snow guard a base plate in combination with a standard pivotallysecured thereto and a brace or bratket pivotally secured thereto andmeans for securing said brace and standard for the purpose specified.

I 3, In a snow guard an inverted U shaped metal standard, a metal baseplate which is secured to the roof, said metal standard being pivotallyconnected at its lower end to said base plate, openings through sides ofstandard for guard pipes or rods, pipes or rods passing through saidopenings in standard and a brace pivotally secured to the abovementioned base plate and adapted to be socured to said standard atdifferent points throughout its length for the purpose of holdingsaidst-andard (when secured to the roof) in a perpendicular position andat a greater or less angle with said base plate (according to the pitchof the roof), as shown and specified.
